From Delphi to C# for DummiesMentioning MSDN and similar sites makes a lot of sense. Regarding interfaces there are some differences I want to mention. You can cast an interface to an object without hacks for instance. Further they are ref counting manually all the time which is no good idea to begin with. But I think you are right and it comes down to creating trust in garbage collector. Further, Zoology seems not be very popular, I take it. ;)
